At a glance
- In November 2025, Japan approved a large economic package combining government spending, tax reductions and support for households and businesses.
- The package included about ¥17.7 trillion of General Account measures and about ¥21.3 trillion of fresh fiscal injections when tax cuts and Special Accounts were included.
- Measures included electricity and gas subsidies, local government grants, child support, tax reductions and investment in areas such as AI, semiconductors and infrastructure.
- The policy is expansionary because higher government spending and lower taxes can increase aggregate demand, real output and employment.
- The main evaluation is whether the extra demand supports growth without adding too much inflation or worsening Japan's already high public debt.
Background
In late 2025, Japan was experiencing moderate economic growth, but households were still being affected by rising prices and weak real purchasing power. The government also wanted to increase investment in strategic industries and infrastructure.
Expansionary fiscal policy is when the government increases spending, reduces taxes, or does both in order to raise aggregate demand. Higher government spending directly increases aggregate demand, while tax cuts can increase households' disposable income and consumption.
If there is spare capacity in the economy, the initial increase in spending can lead to a larger final increase in national income through the multiplier effect. However, if the economy is already close to full capacity, additional demand may create more inflation instead of a large rise in real output.
What happened
On 21 November 2025, the Japanese government approved its Comprehensive Economic Measures to Build a Strong Japanese Economy.
The package included about ¥17.7 trillion of General Account measures. Once tax reductions and Special Account measures were included, the government estimated fresh fiscal injections of about ¥21.3 trillion. Including fiscal investment and loan programmes, the wider fiscal measures reached about ¥25.5 trillion.
The package included direct support for households facing higher prices. The supplementary budget allocated about ¥529.6 billion for electricity and gas bill support, ¥367.7 billion for child-rearing support payments and ¥2 trillion for local government grants. The government also introduced tax reductions, including cuts linked to gasoline and income tax.
At the same time, about ¥6.43 trillion of supplementary-budget spending was directed towards strategic and growth-oriented investment, including AI, semiconductors, shipbuilding, research, critical minerals and infrastructure.
The FY2025 supplementary budget added about ¥18.3 trillion of General Account expenditure in total. Around ¥11.7 trillion of this was financed through additional government bond issuance.

Using this in the exam
Use this case in an answer about expansionary fiscal policy.
Start by explaining that Japan increased government spending and reduced some taxes. Higher government spending directly raises aggregate demand, while tax reductions can increase disposable income and consumption. In an AD-AS diagram, this shifts AD to the right, increasing real output in the short run if there is spare capacity.
You can also explain the multiplier effect. Government payments and investment create income for households and firms. Part of this income may then be spent again, creating further rounds of consumption and a larger final increase in national income.
For evaluation, discuss inflation, government debt and time lags. If Japan is already operating near full capacity, extra demand may mainly increase the price level. Borrowing also increases debt and future interest costs. Some investment measures may take several years to affect output.
Do not treat the full ¥25.5 trillion headline figure as immediate government spending on aggregate demand. It also includes fiscal investment and loan programmes. The clearest direct fiscal figures are the ¥17.7 trillion of General Account package measures and the ¥21.3 trillion of fresh fiscal injections including tax cuts and Special Accounts.

Questions this example can answer

- Discuss whether expansionary fiscal policy is an appropriate response when households face weak real incomes and rising prices.
Evaluation
Arguments in favour
Government spending can raise aggregate demand
Household support, local government grants and public investment directly increase spending in the economy. This can raise firms' revenues, real output and employment when spare capacity exists.
Tax reductions can support consumption
Lower taxes increase disposable income for households. If households spend part of this extra income, consumption rises and shifts aggregate demand to the right.
Investment can also improve long-run productive capacity
Spending on infrastructure, AI, semiconductors and research may increase productivity and productive capacity over time. This means part of the package may affect both short-run aggregate demand and long-run aggregate supply.
Arguments against
Extra demand may increase inflation
If Japan has little spare capacity, a large increase in aggregate demand may raise the price level more than real output. The IMF later assessed Japan as operating above potential and warned against further fiscal loosening.
Borrowing adds to an already high public debt
The supplementary budget required about ¥11.7 trillion of additional government bond issuance. With gross public debt around 203% of GDP in 2026, higher borrowing can increase future interest costs and reduce fiscal space.
Fiscal policy can face time lags
Some household support can reach consumers quickly, but infrastructure and strategic investment projects may take years to plan and complete. Their effect on real output may therefore arrive after economic conditions have changed.
Context and assumptions
The multiplier depends on how much households spend
If households save much of the tax relief or transfers, or spend the money on imports, the multiplier will be smaller and the effect on Japanese output will be weaker.
Not every part of the package is short-run stimulus
Some measures are aimed at long-term resilience and productive capacity rather than immediate household demand. The economic effect therefore differs across parts of the package.
The effect depends on the state of the economy
Expansionary fiscal policy is more likely to increase real output when there is a large negative output gap. When the economy is already close to potential output, inflation and crowding-out risks become more important.
